SPECIFICATION forming part of Letters Patent No. 784,263, dated March'7, 1905.

Application filed April 27, 1903. Serial No. 154,383. I

To (all whom it may concern:

Be it known that 1, JOHN J. HEYS, of Lynn, in the county of Essex andState of Massachusetts, have invented certain new and useful Im- 5provements in Stitch-indenting Machines, of

which the following is a specification.

This inventionhas relation to power-machines, and its objects aremanifold.

Primarily, the object of the invention is to m provide certainimprovements in that class of machines comprising a movabletool-carrying head and power-driven mechanism by means of which theapplication of power may be more readily controlled and the actuation ofthe I 5 head made simultaneous with the clutching or unclutching of thepower transmitting mechanism to the operating parts of the machine.

Secondarily, the invention has for its obj eet 20 to provide certainimprovements in indenting or analogous machines for rendering them moreeflicient in operation and simpler and more durable in construction.

Referring to the accompanying drawings,

2 5 Figure 1 represents in side elevation a machine embodying theinvention. Fig. 2 represents an elevation from the other side. Fig. 3represents a section on the line 3 3 of Fig. 2 looking in the directionof the arrow. Fig.

Fig. '7 represents an enlarged section on the line '7 7 ofFig. 6. Fig. 8 repre- 3 5 sents the mechanism for controlling the clutchdevices. Fig. 9 represents the sainemechanism with the addition of themechanism for controlling the movable head.

For convenience the invention is illustrated 4 as embodied in astitch-indenting machine; but it will be understood that so far as thegeneral features of the invention are concerned they may be as readilyembodied in other forms of the machine and that the terms 45 which areemployed are for the purpose of description and not of limitation.

On the drawings a machine is shown as being provided with a tubularstandard or base 10, supported by legs 11 11 12, arranged in I Figs. 1,2, and 3.

tripodal form. On the top of the standard is placed a frame comprising abase 13, which is extended forwardly, and two uprights 14 15. In ears orlugs projecting upwardly from the uprights 14 there is a movable head151, said head having the conformation illustrated in This head isutilized for carrying the operating-tool. The pivot upon which it issupported is indicated at 16. The front end of the head 151 is arrangedin a guideway formed by slotting the upper end of the upright 15, asshown in Fig. 3, and it is supported by an adjustable Screw 17, passeddownwardly through a lug on one side of the end of the head 151 andresting upon the top of the upright 15. The said screw is provided witha hand-wheel 18. by means of which it may be more easily rotated, and islocked in position by a lock-nut 19.

In the frame is journaled a power-shaft 20, from which power istransmitted to the operating-tool carried by the movable head. A pulley21 is journaled loosely on the shaft and is adapted to be moved intofrictional engagement with the clutch member 22, rigidly sccured to theshaft. For coaction with the clutch member 22 there is a complcmentalmember 23, connected to or forming a part of the pulley 2.1; but it willbe understood that any other clutching mechanism may be employed in lieuof that shown. Moreover, the clutch member may be splined to and axiallymovable on the shaft, as commonly the case with machines of thischaracter.

Mounted in the movable head 15 is a shaft 25, which projects beyond theend of the head and is provided with a suitable operating-tool. Thatform of tool illustrated in Figs. L to 7, inclusive, is moreparticularly adapted for indenting soles. It is indicated at 26 and isprovided with a plurality of indenting edges or teeth. The tool issubstantially in the form of a frusto-conc with the base out, so thatthe teeth converge toward a common center coincident with the axis ofthe shaft 25. The tool is partially inclosed by an angular guard 28,which is cutaway, as at 29, to expose the operative portion of the tool.he end face of the guard forms a gage to bear against the 2 upper of theshoe, while the lower edge 31 bears against the projecting edge of thesole, which is indented by the tool. The shaft 25 is actuated from theshaft by means of the pinion 32 and the gear 33, and by reason of thepivotal connection of the head with the frame the head may be movedupwardly a limited extent to carry with it the shaft and the tool 26without the gears 32 33 becoming unmeshed.

Connected to the head by a stud 34 is a rod 35, (see Fig. 2,) whichextends downwardly loosely through the base 13 of the frame and which isthreaded at its lower end to receive a nut having a hand-wheel 36 formedon or secured thereto. Between the nut and the base 13 is-a spring 37,so that the rod 35 and movable head are both held yieldingly downward,whereby the set-screw 17 normally rests upon the top of the standard 15,as described. For the purpose of lifting the rod 35, so as to raise thehead, and thereby the too], for the insertion of the work under thelatter there is pivoted upon the frame a lever 38, whosefront endprojects under the stud 39 on the rod 35. The rear end of the leverisconnected by a rod 48 with an arm 41 on a treadle 42, projecting forwardfrom the machine between the legs 11, as best shown in Fig. 9. The arm41 of the treadle 42 is pivotally connected by a stud 43 with a link44,'pivoted at its end upon a stud 45, secured in the ear or lug ontheleg 12. When the treadle 42is depressed, the lever 38 is rockedaboutits pivot 46, so as to lift the rod 35 and with it the head and thetool.

Reference has been hereinbefore made to the pulley 21 and the clutchmember 22. This clutch is operated by the treadle-42, as follows: Thehub 47 of the pulley is circumferential] y grooved to receive the stud48 on the bifurcated end of a lever 49, fulcrumed upon a stud 50 on. thestandard 10 and having its lower portion in engagement with the end ofan arm 51, which is substantially a continuation of the treadle 42. Aspring 52 connects the lower end of the lever 49 with a projection 53 onthe tripodal base of the standard. Consequently when the treadle 42 isdepressed the link 44 swings downward upon its pivot 45 and the arm 51of the treadle forces the lower end of the lever 49 rearward against thetension of the spring 52, so as to force the upper end of said lever 49to the right in Fig. 2 and to the left in Figs. 8 and 9, so as tounclutch the pulley 21 and the clutch member 23 from the clutch member22. The upper end of the lever 49 is forked, as has been stated, and oneof its forks, as shown in Fig. 1, carries an automatic stopping deviceconsisting of a friction member 5, which upon the depression of thetreadle comes into frictional engagement with the face of the gear 32,so as to immediately stop its rotation. Therefore when the treadle isdepressed the shaft 20 is unclutched from the pulley, the shaft isstopped from rotation, and at the same time the movable head whichcarries. the tool is raised. When the treadle is released, the headdrops to position under the tension of the springs 27 52 (the spring 52having returned the lever 49 to normal position) and the pulley isclutched to the shaft, whereby the latter immediately rotates.

The work-support which coacts with the tool consists of a peripherallymilled or roughened wheel 60. This is journaled in an oscillatory yoke61, supported by trunnions 62 in diverging arms 63, formed on theupright 15. The yoke 61 has an arm 63, which projects into the spacebetween the two oppositelyarranged screws 64 65, threaded into lugs 6667 on the upright 15. Each screw has a locknut 68. By adjusting thesetwo screws 64 vertically, either upward or downward, the yoke and thework-support 60 may be adjusted about the axis of the trunnion 62, so asto lie horizontally or else at an inclination to the horizontal, so asto vary the angularity of the support and the tools.

From this description of the machine it will be seen that the normalposition of the various parts is that in which they are when operatingon the work and that to move them to inoperative or abnormal position itis necessary to depress the treadle. This is in contradistinction tothose machines in which it is necessary to depress the treadle in orderto move the various devices to operative position and to hold themthere. Consequently with a machine of this character the operator is notrequired to exert his muscular force when the machine is operating, andis therefore able to stand securely on both feet and be thereby savedfrom unnecessary fatigue.

Having thus explained the nature of the invention and described a Way ofconstructing and using the same, although without attempting to describeall of the forms in which it may be made or all the modes of its use, Ideclare that what I claim is- 1. A machine comprising a movable headprovided with a rotary instrumentality to engage the work, a shaftconnected to said instrumentality to rotate it, a power shaft, clutchmechanism on said shaft, driving connection between said shafts, andmeans for simultaneously moving said head to inactive position andoperating the clutch to stop the rotation of said instrumentality.
